Cloud Peak Energy

Cloud Peak Energy Inc. is a company headquartered in Gillette, Wyoming which mines coal in the Powder River Basin. The company was formed as a corporate spin-off from Rio Tinto Energy America in 2009. In its 2009 Annual Report Rio Tinto stated that it held a 48.3% stake in Cloud Peak Energy and its directly owned mines. Cloud Peak Energy also has a 50% stake in the Decker Coal Company, which operates the Decker Mine in Montana.

According to The Guardian, Cloud Peak Energy Inc was responsible for 0.1% of global industrial greenhouse gas emissions from 1988-2015.

In May 2019, Cloud Peak Energy filed for bankruptcy. An analyst pointed to severe declines in demand for Powder River coal from markets in East Asia and the United States.
